His show ends with a squirt from his mouth and a three-metre flame.Mr Finnegan showed off his self-taught talents for the first time in Toowoomba at his new workplace, the Olive Branch Lounge Bar and Restaurant, during Melbourne Cup celebrations.

Although he has only been with the Ruthven St eatery for two weeks, his antics have caused quite a stir.

"Before I put the menu out, I thought it would take people a while to get used to it," He said.

"But the cocktails are literally flying out the door.

"It's like what they say: 'stack them high, watch it fly'."

But it is not just the 25-year-old's showman-like skills that are causing a fuss, it is also his creations.

Like a chef might craft his food, Mr Finnegan spends a lot of time considering his cocktail recipes and menu.
